into the long lead-in. causing objectionable noises
throughout the FM band. In such cases. replace the con-
ventional lead-in with shielded 300~ohm twin-lead (avail-
able at major electronic-pans dealers). Connect the
lead-in's two signal conductors to the receivers FM ANTt
terminals in the usual manner; connect the shield to the
GND terminal next to the AM ANT. terminal.

AM ANTENNAS

It AM reception is marred because you live in a steel-
lrame building. or it you want to supplement the built-in

AM antenna lor improved reception ot weaker stations.
loosen the AM ANT. and GND screws (Figure 1) and
swing the link between them out of the way. Retlghten
the GND screw and connect in to 20 leet ol insulated.
flexible. single-conductor wire to the AM ANT. terminal,
Keep this wire away trom all speaker. audio, and power
cables. Run the wire in a straight line along a non-
metal/Io baseboard or under a rug. In some cases. recep-
tion may be turther improved by draping the wire out a
window or by connecting it to an outdoor whip or rod
antenna.

HEADPHONES AND EXTRA SPEAKERS

WARNING: This receiver has an extremely high music-power output. Make sure that each at your
remote speakers can sately handle at least one-haII the music-power rating on this manual's TECHNICAL
SPECIFICATIONS page. (The Operating Instructions tor all FISHER speakers state their maximum power-
handling capacities.) It your speakers cannot handle this much power. do not turn the receiver's VOLUME
control up too high unless you play your remote and main speakers simultaneously. FAILURE TO
OBSERVE THIS PRECAUTION MAY PERMANENTLY DAMAGE YOUR SPEAKERS!

HEADPHONES

For private listening to all program sources. you may plug
a pair oi FISHER headphones (or other similar high-qual-
ity Iow- or medium-impedance devices) into the PHONES
jack on the control panel. Almost all commercial stereo
headphones are equipped with the proper type at plug to
tit this jack. In the rare event that yours are not. obtain a
standard l/A-inch three-pole phone plug and connect it to
the phones as shown in Figure 3.

When using the headphones for the Iirst time. turn the
VOLUME control to minimum and set the SPEAKERS
switch OFF before plugging in the phones Readjust the
VOLUME control tor a comlortable headphone listening
level and use this setting (or future relerence.

CAUTION: Do not leave the headphones plugged In
when playing the speakers at high volume levels. The
large amounts at audio power required by the speakers
at these levels can overload and damage the phones.

CENTER OR MONO REMOTE SPEAKER

The receiver's CENTER SPKR terminals (Figure 1) will
provide a monophonic speaker output (with the link be-
tween the right-hand and middle terminals closed) when-
ever you set the SPEAKERS switch to MAIN + CENTER
or to ALL. This output is a blend, or composite, ol the
IeIt- and right-channel signals and may be used tor either
one ol two purposes:

- To drive a center-till' speaker in your main listening
room if excessive main-speaker separation causes an
exaggerated hole' in the middle of the stereo sound pat-
tern.

' To drive a monophonic remote speaker in another
room. It you choose this option and also connect stereo
remote speakers. this will permit remote listening In
two extra rooms (mono in one, stereo in the other).

(1) If you are using the speaker in the main listening
room. place it midway between the main speakers and
as close as possible to ear level. (The center speaker
should be Identical or similar to the main speakers for
best results.) It you are using it as a mono remote

speaker. place It in any suitable spot in the remote loca-
tion.

(2) It the speaker is 50 feet or less lrorn the receiver.
use the cable supplied with the speaker or ordinary No.
18 two-conductor lamp cord or antenna twin-lead tor
the connections. For longer distances. use heavy»duty
cable (at least No, 16), Cut the cable to the desired
length but leave some slack in case you want to change
speaker location slightly. Strip about halt an inch oi
insulation from both ends of each conductor and twist
the bare wires to gather up loose strands, Look tor some
sort ol marking on the cable that distinguishes one
conductor trom another: a distinctive color. stripe. or
raised ridge on one of the insulators. a thread underone
ot the insulators. or a dillerent color for each wire. This
will help you to phase' the speaker properly In step 3.

(3) Close the link between the right-hand and middle
CENTER SPKR terminals. Connect the speaker to the
receiver as shown in Figure 1 and tighten all three ter-
minals. It you are using the speaker in the main listening
room. make sure that its COM, GND. C. G. or black ter-
minal goes to the receivers COM terminal, (The center
speaker must be in phase with the main speakers tor
correct stereo perspective and good bass response.) It
you are using it as a mono remote speaker, phasing is
unimportant. In either case. make sure that the bare
wires at the ends 01 the cable do not touch each other,
adjacent terminals. or the receiver chassis.

NOTE: Should you ever disconnect the center speaker.
remember to reopen the CENTER SPKR link and swing
it out 01 the way.

STEREO REMOTE SPEAKERS

The REMOTE and adjacent COM terminals on the LEFT
SPEAKERS and RIGHT SPEAKERS terminal strips (Fig-
ure 1) provide convenient means for connecting a pair oi
remote extension speakers. This arrangement will enable
you to enjoy stereo sound in another room ot your home
when you set the SPEAKERS swltch to REMOTE or ALL.

CAUTION: Never connect the Lelt Speakers and Right
Speaker: REMOTE terminals to each other. Also. bolero
